Overmould collaborate with Combined Test Solutions to improve the Smart-Lights™ device

Combined Test Solutions is the leading UK provider of test equipment and instruments. We were asked to overmould two of their test products, the first being a Smart-Light, a tool for automated and quick test set up and fixturing of large harness tester interfaces.
Tim Morris of CTS explains the problems experienced before using the Low Pressure Overmoulding process provided by Overmould, how this proved to be the solution and why the chosen overmoulding material was used.

Low Pressure Moulding Toolsets

Design & Manufacture of Low Pressure Moulding Mould Sets & Tooling

Mould sets for low pressure overmoulding are normally manufactured from aluminium and precision-machined to form the features of the desired part. Aluminium is well suited for mould-set manufacturing due to its excellent heat transfer properties (i.e. short cycle times) and is economical from a cost and time perspective.

Aluminium mould-sets are relatively soft and care must be taken not to damage the cavity surface. If the component to be over-moulded has steel or hard glass filled components, it is recommended to have steel inserts in the mould cavity to reduce any wear on key tool components. This is generally required when moulding connectors. Mould-sets can also be manufactured from tool steel such as P-20. It may be required to cross drill steel mould-sets to ensure sufficient cavity cooling.

Overmoulding versus potting

Low Pressure Overmoulding versus Potting or Encapsulation

In electronics, encapsulation or potting is the process of pouring liquid resin over electrical and electronic components, circuit boards and completed electronic assemblies for electrical insulation and to protect the product against thermal shock, vibration, moisture and corrosive substances. Low Pressure Overmoulding is an injection process where the PCB assembly or electronic part is placed in a specially manufactured aluminium mould tool, and completely surrounded with a liquid compound that effectively forms the housing for the device. We compare the two processes.
